[0021] Please see Figure 1-7 This utility model provides the following technical solution: a municipal construction enclosure, including a base 1 and a baffle 2, and also including a mounting plate 3 and a protective net 4. The baffle 2 is slidably mounted on the base 1. The baffle 2 and the base 1 are provided with a series of matching limiting holes 21. Screws are threadedly installed on the limiting holes 21. A support plate 12 is hinged to the bottom of the side wall of the base 1. Two telescopic support rods 13 are hinged to the support plate 12. A fixing seat 14 is provided on the telescopic support rods 13. A fixing plate 11 is provided on the side wall of the base 1. 2 and the fixed base 14 are provided with holes that mate with the pin holes provided on the fixed plate 11. A self-rewinding reel 41 is installed on the base 1. A protective net 4 connected to the baffle 2 is wound on the self-rewinding reel 41. A mounting plate 3 is provided on the top of the base 1. Several threaded rods 32 are rotatably installed on the mounting plate 3. Threaded sleeves 35 are threadedly installed on the threaded rods 32. Toothed rings 34 are provided on the side walls of the threaded rods 32. Toothed belts 33 pass around all the toothed rings 34. The bottom of the base 1 is provided with grooves that mate with the mounting plate 3 and the threaded sleeves 35.
[0022] The construction site can be sealed off by the baffle 2. The side wall of the groove on the base 1 where the baffle 2 is installed has a protrusion, and the side wall of the baffle 2 has a groove that mates with the protrusion on the side wall of the groove on the base 1. The mating of the groove and the protrusion on the side wall of the baffle 2 serves as a limiting mechanism, ensuring the stability of the baffle 2 after it is installed on the base 1. The limiting holes 21 are located on the side wall of the groove on the side wall of the baffle 2 and on the protrusion on the side wall of the groove on the base 1. Screws are threaded onto the overlapping limiting holes 21 on the base 1 and the baffle 2. The baffle 2 is fixed in place by the screws and the limiting holes 21, ensuring its stability after installation on the base 1. The baffle 2 is connected to the protective net 4, which is wound around a self-rewinding roll. When the position of the baffle 2 on shaft 41 is insufficient to protect the construction site, the screw and the limiting hole 21 are released, the baffle 2 is released from its fixation, and the baffle 2 is pulled upwards. As the baffle 2 moves, it pulls the protective net 4, which seals the space between the base 1 and the baffle 2, ensuring the protective effect of the device. The upward movement of the baffle 2 increases the height of the device and improves its working effect. When the user wants to store the device, the baffle 2 is moved downwards. At this time, the self-rewinding shaft 41 will automatically rewind the protective net 4, making it easy for the user to store the device. The support plate 12 is hinged to the base 1. When the device is in use, the support plate 12 is rotated to make it fit against the ground, increasing the ground contact area of the device and improving its effectiveness. To ensure the stability of the device, the installation method of the support plate 12 guarantees its working effect. When the device is in the stored state, the support plate 12 is fixed in place by the cooperation of the fixing pin with the fixing plate 11 and the support plate 12, ensuring the stability of the support plate 12. After the support plate 12 is unfolded, the length of the telescopic support rod 13 is adjusted by rotating it. The telescopic support rod 13 can be fixed in place by the cooperation of the fixing pin with the fixing plate 11 and the fixing seat 14. The cooperation between the support plate 12, which is in contact with the ground, and the fixed telescopic support rod 13 acts as a support base 1, ensuring the stability of the device during use. If the height of the baffle 2 is still insufficient to block after adjustment, the other baffle can be blocked by the cooperation of the mounting plate 3 and the groove that mates with it. A base 1 is mounted on top of the baffle 2, further enhancing the device's blocking effect. A threaded sleeve 35 is threadedly mounted on a threaded rod 32. When the user rotates the threaded rod 32, the threaded sleeve 35 moves along the threaded rod 32 under the action of the threads. The moving threaded sleeve 35 enters the interior of its mating groove, improving the stability of the base 1 after it is mounted on the baffle 2. Several threaded rods 32 are connected by a toothed belt 33 and a toothed ring 34. When the user rotates one threaded rod 32, the remaining threaded rods 32 are rotated along with it by the toothed belt 33 and the toothed ring 34, achieving synchronous rotation of all the threaded rods 32. This improves the efficiency of the threaded sleeve 35 entering its mating groove and increases the efficiency of the user connecting the two devices.The threaded sleeve 35 has a protrusion on its side wall, and the groove for mounting the threaded sleeve 35 has a groove on its side wall that mates with the protrusion. The engagement of the protrusion and the groove serves to limit movement, ensuring that the threaded sleeve 35 does not disengage from the groove during movement, thus guaranteeing its stability.
[0023] Specifically, the fixing seat 14 is rotatably mounted on the end face of the telescopic support rod 13, and the end face of the fixing seat 14 is provided with a protrusion with a width that is half the width of the telescopic end of the telescopic support rod 13.
[0024] The fixed base 14 is rotatably mounted on the telescopic support rod 13. The user can adjust the position of the fixed base 14 according to actual needs. When the devices are assembled, the upper support plate 12 is released from its fixing position, and the support plate 12 is rotated to make it fit against the lower baffle 2. The upper telescopic support rod 13 is rotated so that the two fixed bases 14 are in an overlapping state. The shape of the top protrusion of the fixed base 14 ensures that the top protrusions of the two fixed bases 14 can overlap. The pin holes on the overlapping fixed bases 14 overlap, and the two fixed bases 14 can be fixed together by the fixing pin, thereby realizing the connection of the two telescopic support rods 13. The side wall of the pin hole of the fixed base 14 is provided with a groove. The cooperation between the fixing pin and the groove on the side wall of the pin hole plays the role of fixing the telescopic support rods 13 that are connected together, ensuring the support effect of the connected telescopic support rods 13 on the device, and thus ensuring the stability of the installed device.
[0025] Specifically, one end of the self-rewinding reel 41 penetrates the side wall of the base 1, and a handle is provided on the end face of the self-rewinding reel 41.
[0026] During prolonged use of the device, the automatic winding of the self-rewinding shaft 41 around the protective net 4 may be affected. In this case, the user can manually control the self-rewinding shaft 41 to rotate through the handle on the end face of the protective net 4, thus ensuring the winding effect of the self-rewinding shaft 41 around the protective net 4.
[0027] Specifically, a storage slot 42 is provided on the top surface of the base 1.
[0028] When the user moves the baffle 2 back to its original position, the protective net 4 that is not completely rolled up by the self-rewinding roller 41 will accumulate inside the storage slot 42. This prevents the protective net 4 that is not completely rolled up from being clamped by the base 1 and the baffle 2, and prevents the self-rewinding roller 41 from affecting the winding of the protective net 4. The storage slot 42 extends through one side wall of the base 1. The shape of the storage slot 42 makes it easy for the user to clean up any debris that enters the storage slot 42. When the user adjusts the position of the baffle 2, the storage slot 42 provides a position for the user to apply force to move the baffle 2, making it easy for the user to adjust the position of the baffle 2.
[0029] Specifically, a roller is provided at the edge of the groove through which the protective net 4 passes through the base 1, and the protective net 4 passes around the roller.
[0030] The rollers installed at the edge of the groove through which the protective net 4 passes through the base 1 serve as guides, reducing wear on the protective net 4 during its pulling process. As the protective net 4 moves, it rotates along with the rollers, which reduces damage to the protective net 4 during the use of the device and extends its service life.
[0031] Specifically, the top surface of the mounting plate 3 is provided with a fixing block 31, and the bottom of the base 1 is provided with a groove that cooperates with the fixing block 31.
[0032] The fit between the fixing block 31 and the groove on the bottom surface of the base 1 serves as a limiting mechanism, and the fit between the fixing block 31 and the groove further enhances the stability of the two devices after they are installed together.
[0033] Specifically, the support plate 12 and the hinge seat for mounting the support plate 12 are provided with several matching pin holes on their side walls.
[0034] When the device is in use, the support plate 12 is fixed by the cooperation of the fixing pin with the pin hole provided on the hinge seat for mounting the support plate 12, which further improves the stability of the support plate 12 during the use of the device. The position of the pin hole provided on the support plate 12 ensures that when the upper support plate 12 and the lower baffle 2 come into contact after the devices are installed together, the support plate 12 is fixed by the cooperation of the fixing pin with the pin hole provided on the hinge seat for mounting the support plate 12, which further improves the stability of the installed devices.
[0035] The working principle and usage process of this utility model are as follows: When using the device, release the fixing of the support plate 12, rotate the support plate 12 to a state of being in contact with the ground, rotate the telescopic support rod 13 to adjust the length of the telescopic support rod 13, and fix the telescopic support rod 13 by the cooperation of the fixing plate 11, the fixing seat 14 and the fixing pin. The cooperation of the support plate 12 and the telescopic support rod 13 plays the role of supporting the base 1, ensuring the stability of the device during use. When adjusting the height of the device, release the cooperation between the screw and the limiting hole 21, move the baffle 2 upward. As the baffle 2 moves, the protective net 4 is pulled out. The pulled-out protective net 4 will seal the space between the base 1 and the baffle 2, ensuring the working effect of the device. Fix the moved baffle 2 by the cooperation of the screw and the limiting hole 21. The height of the device is not... When the two devices are in place, the base 1 is installed on the baffle 2, the mounting plate 3 and the fixing block 31 are inserted into the groove that mates with it, the threaded rod 32 is rotated, and all the threaded rods 32 rotate synchronously under the cooperation of the toothed belt 33 and the toothed ring 34. The threaded sleeve 35 moves along the threaded rod 32 under the action of the thread, and the moving threaded sleeve 35 enters into the groove that mates with it. The devices installed together are fixed. The fixing of the upper support plate 12 is released, the telescopic support rod 13 provided on the support plate 12 is rotated, the fixing seat 14 is rotated, and the fixing seat 14 is fixed by the fixing pin. The two telescopic support rods 13 on the same side are connected together. The connected telescopic support rods 13 serve as a support device. The upper support plate 12 is fixed by the fixing pin.
